(VEN) - Bach Long Vi Island in Hai Phong City has proved to be an ideal location for abalone farming. Therefore, the Seafood Research Institute in collaboration with the Hai Phong Young Volunteers Association and Bach Long Vi Island District’s People’s Committee have implemented many abalone breeding, conservation and production projects.

According to Engineer Lai Duy Phuong from the Seafood Research Institute, Vietnam has eight species of Haliotis abalone. But Haliotis persicolor has the highest economic value.
This abalone species is distributed mainly in northern seas, especially at Bach Long Vi, an island located in the Tonkin Gulf very far from the inland where is considered with favorable conditions for abalone development such as stable salinity, clean water, and rock structured floors.
According to the Seafood Research Institute’s survey data, annual abalone exploitation at Bach Long Vi Island reached about 37 tonnes before 1987. However, over the years without abalone conservation and breeding plans, annual catches only reached five tonnes as of 1992, and approximately one tonne as of now.
To address this, Bach Long Vi Island District’s People’s Committee has conducted a number of abalone breeding, conservation and production projects such as 6m deep seawater management model, abalone protection zone establishment, and community-based abalone resource management model. One of the key projects is the Bach Long Vi Abalone Breeding and Production Technical Demonstration Model coordinated by the Seafood Research Institute in collaboration with the Hai Phong Young Volunteers Association and Bach Long Vi Island District’s People’s Committee during the 2012-2015 period.
The project has successfully produced 125,611 Haliotis persicolor seeds with stocking sizes from 0.9 to 1.3cm in service of commercial farming and conservation of renewable natural resources. Commercial farming models aim at meeting abalone demands from domestic and foreign markets and supporting Bach Long Vi abalone branding in the near future.
The domestic annual abalone seed production only meets below 0.15 percent demand, while imports proved too expensive. So, it is important to increase abalone seed production, said Hoang Dinh Chieu from the Seafood Research Institute.
Bach Long Vi Island District has assigned 200ha of 6m deep seawater surface (raising the country’s abalone farming area to 350ha) for 40 local households to farm abalone. It is estimated that the annual income per household will reach VND35 million. This is a good beginning for abalone aquaculture development on Bach Long Vi Island.
According to Bui Duc Quang from Bach Long Vi Island District’s People’s Committee, the district is aiming to produce more than 100,000 Haliotis persicolor seeds for commercial farming and conservation activities. Bach Long Vi abalone branding will also be increasingly promoted on media./.
According to the Seafood Research Institute, global annual abalone consumption has reached 70,000 tonnes, including 56,000 tonnes consumed by Japan, China, the Republic of Korea, Hong Kong, and Chinese Taipei and the remainder by European countries, US, and Canada. Vietnam can absolutely promote abalone farming to supply the world market thanks to sea and island advantages.
